lNOZZLE FOR DRINKING-FOUNTAINS.

SPECIFICATION forming part of Letters Patent o. 685,675, dated October 29, 1901. Application filed March 23, 190l1. Serial No. 52,482. (No'model.)

To all whom, it may concern:

Be it known that I, WILLIAM HENRY DE- 'WAR,a citizen of the United States, residing'atthe borough of Manhattamin the city,county, and State of NewYork, have invented an Improvement in Nozzles forDrinking-Fountains,

vOf which the following is a specification.

My invention relates to au improvement in nozzles for d rinking-fountains. These nozzles are usually Vemployed inv connection with a basin for catching surplus water and are especially adapted for use in schools. ,Devices of this general character haveheretofore been employedE In these devices, however, it has been possiblefor children to play with the supply of Water by putting the finger over the end of the nozzle, and so reducing the supply and increasing the pressure, and thus forcing the Water to greater distances, delivering the same upon one another and beyond the limits of the basin.

The Object of my present invention is to improve the nozzles heretofore employed, to simplify the construction, and to lessen the liability, or, in other words, make it substantially impossible for children to thus play with the Water.

In carrying out my invention I employ a head and connected sleeve, with a grip-ring and supporting-arms preferably made integral with the head. A tubular stem is also made integral with the head, which exteriorlyis preferably conical and provided with an opening at the apex,which extends through the tubular stern, and a perforated cap is connected to the lower end of the tubular stem, and these parts move vertically together as a unit with pressure upon the'grip-ring, which pressure moves a valve within the hollow standard to admit the water through the said cap and tubular stem and deliver the same from the opening in the head. In this way a vertically-movable stream of water of a height according to the pressure emerges from the opening in the head and which can be drank at the fountain. The sleeve connected to the head is made with vertical grooves or equivalent devices, and the tubular stem of the head is made with downwith greater force will flow back through the-` openings in the tubular stem into the conical head and away bythe grooves in the sleeve and waste into the basin, so that no matter how much the size of the Opening may be reduced by the finger the'water will not flow therefrom with any greater force.

In the drawings, Figure l is a vertical section representing my improved nozzle.` Fig. 2 is a plan of the same. Fig. 3 isa section at w :n of Fig. l; Fig. 4, a section at y 'y of` Fig. 1, and Fig. 5 is a separate plan view of the perforated cap. Y

The head a is hollow, is preferably exteriorly conical, is provided with a tubular stem a', an opening 2 at the apex of the head with integral su pportin g upwardly-extending arms 3, and a grip-ring b, and in said tubular stem there are holes l2 at spaced-apart intervals and placed at downward inclinations, forming communicating passages between the interior of the head a and the opening in the tubular stem a', and I provide a sleeve c below the head and connected thereto by a screw-thread. This sleeve c surrounds the hollow standard d, and its inner face is provided with grooves 13, placed vertically and at spaced-apart intervals, the grooves forming communicating passages from the interior of the head and sleeve to the outside.

The hollow standard (l is provided in its base with an interiorly-threaded opening 4, to which is preferably connected a supplypipe for Water, and a Valve-stem 5 passes through the head above the opening 4 and is adapted, as shown in Fig. l, to permit the water to pass into the hollow standard, or when given a partial turn toclose oif the entrance of water. A valve-seat e is connected by a screw-thread to an internal fiange of the hollow standard d. This valve-scat is in the form of a ring. The valve proper comprises a stem fof X form in cross-section. This passes through the valve-seat c, with a head on the lower end, between which and the uuder surface of the valve-seat is a washer 6. Surrounding the stemf is a spring 7, above which is a washer S, held in place by a pin 9, passing through the stem f. The spring Araises the stem f and holds the washer 6 against the under side of the valve-seat e to close off the water, and when these parts are depressed passage-ways are formed for the entrance of water to the upper part of the standard through the channels of the X-stem f. (See Fig. 4E.)

The sleeve g, of stepped form, screws into the upper part of the hollow standard d and surrounds the tubular stem d', and within this sleeve and around the tubular stem a' is a packing l0 and a packing-ring l1, the adjustment of which packing-ring tightens the packing. In the lower part of the tubular stem a is a perforated cap h, the under surface of which rests upon the upper part of the stem fand is supported thereby.

In the operation of the device as described pressure upon the grip-ring b acts through the head a, the tubular stem ct', and the cap h to force the stem f downward against the spring 7 to open up the passages between the lower and upper parts of the hollow standard, so that water passes from the lower part through the valve-seat e into the Lipper part, from the upper part through the openings in the cap h into the opening-in the tubular stem, and emerges from the opening 2 at the apex of the head a., and the amount of Water and the pressure thereof are regulated by the extent to which the head and parts connected therewith are depressed by means of the gripway no cup, glass, or other vessel is necessary for drinking purposes and there are no metal or other parts that might communicate any germs or other contamination.

The holes l2 in the tubular stem aand the grooves 13 in the sleeve c are employed particularly for preventing children playing with the fountain and by putting the finger over the opening 2 in the apex of the head reducing the opening, and so increasing the pressure and delivering the water at distances beyond the basin provided for catching the same. When this operation is attempted, the opening is reduced and a back pressure established, which causes the water in the tubular stem to flow back through the holes 12 within the head and Waste through the grooves 13 into the basin. In this way no matter what may be the size to which the opening is reduced the pressure is not increased, and the flow of water from the opening 2 is also not increased in its ratio or speed.

I claim as my inventionl. In a nozzle for fountains, the combination with a head, arms and a grip-ring by which the head is movable, of a tubular stem to the head having downwardly-inclined perforations forming communicating passages between the opening in the tubular stem and the interior of the head, and a sleeve connected to the head and forming a downward extension thereof and having grooves in the inner fsurface through which the Water from the said downwardly-inclined holes wastes, substantially as speciiied.

2. A nozzle for drinking-fountains, comprising a hollow standard, `means for connecting the same to the supply of water and for closing off the supply, a head, tubular stem and sleeve connected to the head and vertically movable upon said standard,a valve within the standard depressed by the movement of the head, aihand device for depressing the head, and openings for discharging water from the tubular stem when a back pressure is created, substantially as set forth.

3. Anozzlefordrinking-fountains comprising a hollow standard, a connection thereto from a source of water-supply and a valvestem for closing the same, a spring-actuated vertically-movable valve within the hollow standard for controlling the supply of Water and pressure within the same, a hollow head exteriorly conical and provided with an opening at the apex, an integral tubular stem, a perforated cap upon the lower end of the stem, a sleeve connected to the head and surrounding the hollow standard, arms and a grip-ring integral with the head rising therefrom and surrounding the head, a sleeve within the head surrounding the tubular stem and a packing therein, and means for discharging the Water through the head and sleeve connected thereto when a back pressure is established, substantially as specified.

4. A nozzle for dlinking-fountains, comprisinga hollow stand ard, a connection thereto from a source of water-supply and a valvestem for closing the same, a spring-actuated vertically-movable valve Within the hollow standard for controlling the supply of Water and pressure Within the same, a hollow head exteriorly conical and provided with an opening at the apex, an integral tubular stem,

a perforated cap upon the lower end of thel IOD IIO

the opening in the tubular stem and the interior of the head, and a sleeve with vertical grooves at spaced-apart intervals in the inner surface surrounding the hollow standard whereby when a, back pressure of Water is established at the opening in the head the water wastes through the openings in the tubular stem and the grooves in the sleeve, substantially as specified.
